Re: [Machinekit] problems installing xenomai kernel

[schoone...@btinternet.com]

Hi There are no Xenomai packages for Stretch. Xenomai was initially a way of getting better latency on ARM platforms, notably the BBB Now the rt-prempt kernels (4.4 at least) provide sufficiently good latency for a servo thread, so the later images use rt-preempt. Also later xenomai kernels moved to xenomai3, which is not supported in Machinekit. Xenomai has never been of any use for x86 computers. It does not have good enough latency for software stepping and is completely unnecessary for hardware stepping, where rt-preempt is much simpler and perfectly good. If you want to do software stepping you need to use linuxcnc which still has a rtai kernel Otherwise use rt-preempt with Mesa boards regards On 20/01/18 17:20, Raul Nieves Pardo wrote: hi! i installed debian stretch on a pentium E5300 (features PAE) i run these commands http://www.machinekit.io/docs/getting-started/APT-packages-stretch/ all fine but trying to install the xenomai kernel (http://www.machinekit.io/docs/getting-started/install-rt-kernel-amd64/) "sudo apt-get install linux-image-xenomai.x86-686-pae" returns a not found package error "sudo apt-cache search linux-image-xenomai.x86-686-pae" and "sudo apt-cache search machinekit-xenomai" return  nothing any ideas? thanks!!!
